After hatching, the larva of  T. absoluta passes through four instars. The color of the larvae varies from light yellow to dark brown.

The incubation of eggs (4.3, 4.8 and 5.1) and larval period (10.95, 13.00 and 19.17 days) vary with temperatures of 27, 22.8 and 18.5 ºC, respectively (Coelho & France, 1987, Haji et al., 1988; Imenes et al., 1990).
